Freedom and happiness are won by disregarding things that lie beyond our control.
The soul's impurity consists in bad judgements, and purification consists in producing in it right judgements, and the pure soul is one which has right judgements, for this alone is proof against confusion and pollution in its functions.
Happiness is an equivalent for all troublesome things.
With ills unending strives the putter off.
Appear to know only this--never to fail nor fall.
The wise realize that some things are within their control, and most things are not. They learn early on to distinguish between what they can and can't regulate.
